What is air in the membrane of face after tooth pulled?

Air in the membrane of your face after tooth extraction is called surgical emphysema. It occurs when air escapes into the surrounding of your mouth and face because of the negative pressure created during the procedure. This condition is usually harmless and will resolve on its own within a few days. However , it can cause swelling and discomfort, which can usually be managed with pain medication and cold compresses. In rare cases, surgical emphysema can lead to more serious complications, such as infection, so it's important to follow your dentist's instructions and monitor your symptoms carefully.
